Habitat
This species primarily inhabits tropical and subtropical forests, including rainforests, secondary growth, and forest edges in Central and South America, from Mexico to northern Brazil. They prefer areas with dense vegetation for cover and are often found in trees or near water sources. Robinson's mouse opossum adapts to both lowland and montane forests up to about 2,000 meters elevation.
Diet
Robinson's mouse opossum is omnivorous, feeding on insects like beetles and crickets, fruits such as berries and figs, and occasionally small vertebrates or nectar. They forage primarily at night, using their sharp senses to locate food in trees and on the ground. Feeding behavior includes climbing to reach fruits or pouncing on insects.
Behavior
Robinson's mouse opossum is nocturnal and solitary, spending most of its time in trees where it is agile and adept at climbing. It exhibits territorial behavior, marking areas with scent glands, and is generally not aggressive, often playing dead when threatened. They are opportunistic and curious, frequently exploring new areas for food, but do not form social groups.
Conservation Status
The IUCN classifies Robinson's mouse opossum as Least Concern due to its wide distribution and stable population. Major threats include habitat loss from deforestation and fragmentation, but it adapts well to disturbed areas.
